How long was it before you stopped using Antibiotics and when you started urine therapy? You do realize that it takes time for your body to rid of the Antibiotics you were using?
You should probabaly of waited at least a month without using antiobiotics. You should'nt do urine therapy if your on Antibiotics or other unnatural meds/drugs.
I'm thinking that your urine had the antibiotics you were using in it which made you more sick and that is why it set you back.
